Anybody know of a source of 22/45 complete grip frames ("lower receiver")? Since this isn't the serialized portion of the gun, you should be able to buy them without an FFL. Numrich Arms doesn't stock them. I want to convert my MKII Target to a 22/45.

one negative, its so lite, that it moves more than the steel upper, i hate to say more recoil since its a .22 but you can tell a difference. my wife likes the steel upper better on my Mark IIBut its a blast.
